Personally, I’d say pricing particularly with earlier Ryzen. I went from an i7-860 to a Ryzen 2700, my entire build (except GPU which I carried over) was $461 due to sales (in 2019). Also I wanted higher thread count, something AMD really pushed to normalize and something useful for compiling (and my old CPU having 8 threads is why I was able to use it for so long, experience depended on how the software/game supported it though).

I mean Intel might be more competitive in some cases now and AMD less so (now that they’ve had success) but some of those things might still hold true in some capacity. I think AMD motherboards being cheaper was another thing, but again not sure now.

Some of it is probably also old perceptions mixed with bad PR on Intel’s part (glue comments, CPU with chiller debacle), and I’d imagine worries about E core support for their newer stuff or just power draw.
